COMBINED CAR AND AIR-BRAKE COUPLING.

SPECIFICATION forming part of Letters Patent No. 307,902, dated November11, 1884.

(No model) T0 all whom it may concern:

Be it known that I, JOSEPH F. BA'rcHELoR, a citizen of the UnitedStates, residing at Baltimore, in the State of Maryland, have inventedcertain new and useful Improvements in Cornbined Car and Air-BrakeCouplings, of whicl is accomplished will be described in connccl tionwith the accompanying drawings, which illustrate what is deemed the bestmeans of carrying the invention into effect.

Figure 1 is a side view, partly in section, of the ends of two cars withthe improved couplers connected. Fig. 2 is a top view of two couplersseparated. Fig. 3 is a front end view of brake-coupler. Fig. 4 is alongitudinalvertical section of the brakecoupler. Fig. 5 isa plan viewof the valve.

The letter A designates the end of a car, and B the ordinary bui-'tersbetween the cars. rlhe draw-head O has the usual endwise movement by theoperation of a slot, a, and a fixed bolt, I), passed through the slot. Aspring, c, serves to keep the draw-head pressed endwise toward the endof the car.

The car-couplingE, in this instance, consists of the well-known hooks,which are pivotcd to the draw-head, and thereby have a lateral movement.Any other known suitable form ofcarcoupler may be used instead ofthehooks. Springs to bear on the side of the hooks may be employed, asusual, to keep the couplerhooks engaged, and chains d and the usuallevers (not shown) maybe employed to uncouple the hooks. These partslare all well known. lhe car-coupler draw-head has a hollow front end,C, and a brake-coupling head, F, consisting of any suitable elasticmaterial, like rubber, is fixed to a shank, e, which is adapted to slideendwise into the hollow front of the drawi' head.- A spring, f, withinthe hollow head keepsthebrake-couplingheadprojected. The elastic head Fhas a circular face, g, and a central hole, g', for the passage of thetluid, air, or steam, which operates the brake. Then the brake-couplingheads of two cars come in contact, the springs f will press themtogether tightly, but will yield to allow the elastic head F on each toset against the vouter front end, h, ofthe draw-head, as shown in Fig.l. As the heads are elastic, they will thus, together, and compressedbetween the draw-heads, produce an air-tight connection. The hollowdrawhead has a passage, t', and a port, Z, and between thema valve, 7c.The valve consists of two circular plates, n, o1' one plate and a seatfor it. The plates have two openings or ports, a, and one plate is fixedto a spindle, n, which is adapted to make a quarter-turn. lVhen thevalve is open, the ports n in each plate coincide, and when closed thecut-offs n of one plate cover the ports ofthe other. The spin dle alprojects through the top of the drawhead, and has an arm, at, attached.A spring, or", bears against the arm and keeps the Valve normally open.A lever, n, is pivoted to the car-platform, and projects above it, andachain, nl, connects the lower end of the said lever and spindle-arm. Bythese or equivalent devices the valve may be closed at any time byaperson on the platform. rIhe usual brake-pipeG extends along below thebottom of the car to the brake-cylinder. (Not shown.) As the brake-pipeis immovable, a flexible hose, F, is used to connect the brake-couplingport Z on the draw-head with the said brake-pi pe, there` by providingfor the endwise movement of the draw-head. From this description it willbe seen that when the draw-couplers E on two cars are connected, thebrake-couplers F will also be in Connection, as shown in Fig. 1, andsaid draw-couplers will keep the brake-couplers toget-her.

To insure that thebrakecoupler heads,when approaching each other in theoperation of coupling up, will come together properly, so that theirfaces g will exactly coincide, I employ a curved or slanting guide-arm,I, which projects from one side at the front end of the draw-head. Theoperation of this projecting guide-arm to prevent lateral displacementwill be understood by reference to Fig. 2. As each of two approachingdraw-heads has a projecting guide-arm, I, on an opposite side, neitherdraw-head can deflect laterally. I also employ a groove, j, on the sideof the draw-head opposite that whereon the guide-arm is attached. Aportion of the groove has parallel sides p,- but near the front end ofthe draw-head the sides of the groove curve or spread apart, as at p',to form a Haring entrance. The guidearm of one drawzhead occupies thegroove of the other. The upper and lower curved sides at the entrance ofthe groove serve to direct the arm I into the groove and prevent thedraw-heads from deiiecting vertically. Thus by the guide-arms andgrooves having curved sides or Haring entrance the brake-coupler headsare brought together properly.

In order to provide for connecting one of these brakecouplers with anystyle of V4brakecoupler now in use, a special port, q, is made. A yoke,1', and screw s at the port serve either to stop the port or to connecttherewith an ordinary hose-coupling. By this device a car with mycouplers may be made up in a train with cars with a different coupler.

The couplers are designed for use with air, steam, or vacuum brakes, andmay therefore be used with the Westinghouse automatic brake, for whichit is adapted.

Having described my invention, I claim and desire to secure by LettersPatent ofthe United Statesl. The combination, substantially as setforth, of a draw-head, an elastic coupling for iiuidpressure brakes onthe front end of the draw-head, a connection for the passage of duidbetween the said elastic coupling and the brake-pipe on the car, and acar-coupler to connect the draw-head with another drawhead, whereby whenthe cars are coupled the elastic coupling for the brakes will becompressed between the draw-heads.

2. The combination, substantially as set forth, of a hollow draw-head, acar-coupler attached to said draw-hcad, an elastic brakecoupling head onthe front end of the drawhead, and a hole` in the elastic head, which isin communication with the brake-pipe on the car.

3. The combination, substantially as set forth, of a hollow draw-head, acar-coupler attached to said draw-head, a brake-coupling head having ashank adapted to slide into the hollow draw-head, and a spring to pressthe brake-coupling head outward.

4. The combination, substantially as set forth, of a draw-head, abrake-coupling attached thereto, a valve to open and close the passagein the said brake-coupling, and a 1ever on the car-platform, connectedwith the valve, whereby a person on the platform may at any time open orclose the brake-valve.

5. The combination, substantially as set forth, of the draw-heads, aguide-arm attached at one side, and projecting in front of eachdraw-head, and a fluid-pressure brake-coupling, and also a car-coupler,both attached to a draw-head.

6. The combination, substantially as set forth, of a coupling forfluid-pressure brakes, and a head to which the coupling isattached,having at one side a guide-arm projecting in front and at the other sidea groove for the reception of a guide-arm.

In testimony whereof I ax my signature in presence of two witnesses.
